Specification of Letters Patent.

Patented Apr. as, rare.

Application filed March 21', 1917; Serial No. 156,245.

To all whom it may concern:

DB it known that I, ALBERT PAUL CooHnANn, a citizen of the UnitedStates, and a resident of the borough of Brooklyn, in the county ofKings and city and State of New York, have invented a new and usefulContainer, of which the following is a specification.

' The inven'tionis an improvement in containers and corner-pieces, moreespecially of the type disclosed in my ReissueFatent No. 14,294 of Mayeffect simplification and to provide acorner fastener which can beoperated from the outside and affords more room in the in ter1or.

In the accompanying drawings:

Figure 1 is a perspective View of the con.

tainerpartly assembled; Fig. 2 is an inside view of one of the cornerfastenings; Fig. .3 isa side view of the same; Fig. 4: 1s a section onthe bile 4% of Fig. 2; Fig.

6 is an outside perspective view of an assembled corner; Fig. 6 aninside perspective view of an assembled corner; Fig. 7 is a verticalsection through a bottom corner, assembled; Figs. 8 and 9 are detailviews of the inner member of a corner fastening; Fig. 10 is aperspective View of the box collapsed; Fig. 11 is a verticallongitudinal section through the same; Fig. 12 is a vertical sectionthrough a lower corner, illustrating a slight modification; Fig. 13 is aperspective view of a corner portion of one of the container sectionsformed as in a perspective view of an alternative form of end section;and Fig. 15 is a side view of a slightly different form of nut.

The container is a hollow parallelepiped built up of separate side orwall sections 1, 2, 3, 4, 5 and 6, preferably ofsheet metal and havinginturned edge flanges 7. For purposes of distinction the sections may bereferred to as end sections 1 and 2, side sections 3 and 4, bottomsection 5, and top or cover section 6. 'The flanges enable the sectionsto be mutually staying when erected and afford anchorage for the cornerfastenings as in my prior patents.

The corner fa stenings here employed comprise outer and innerhollowvirtually pyramidal members 8 and 9, fitting the exterior andinterior apical corners of the 1, 191.7, the objectbeing to container.Each inner member has an apical projection 10, in the present instance ascrew stem formed. or united integrally with the member, and the outermember or cap has an apical opening or recess 11 to ltiCGlYG the stem. Aball nut 12 screwed onto the end of the stem and against a flat bearingface 13 on the cap constitutes both a means of applying clamping pressure and a buffer and skid. This nut may have angular wrenclrreceivingfaces 17 formed on a reduced neck, as shown in Figs. 3 and 4:, forexample, or a clamping boss having less projection may he produced asshown in Fig. 15 by forming the wrench faces on one-half of the ball12".

The extreme corners of the sectlons are provided with registering orcomplementary recesses forming openings 14' at the apical corners whenthe container is up, for

the stems 10 to pass through. In one or more of the sections,particularly the cover SQOblOll or the one last applied 111 the closingof the box the ends of the flan 'es ma 7 be separated byspaces or slots15, constituting lateral entrances to such openings, capable of shdmgover the necks of the stems 10 of the inner members 9, which may thus bepo sitioned before the cover is put on. During this operation and untilthe nuts are screwed on, the said inner members may be held in place byvirtue of their stems being a. somewhat tight fit in the corner openingsof the end and necks 16 of these stems may be slightly reduced to passthrough the slot entrances, the outer portions of the stems being largerthan the corner openings,so that the inner members are keyed in placebefore the nuts are put on. Wherever this construction is employed theslots 15 are required.

The sections are preferably so graduated in size that the two sidesections 3 and 4- may nest one into the other in the collapsedcondition, and both into the bottom section, while the end sections 1and 2 nest into each other and both into the side sections, while thetop section fits over all. This involves the end ceived inside the sidesections when erected, as shown in Fig. 1.

Manifestly the order of nesting sizes of the sections and their sidesections 1-4. Or, the a sections being restill retaining the principleof graduated sizes whereby all but one of the flanged sections nestsuccessively together with their flanges all pointing in the samedirection, the last section receiving all of them with its flangespointing in the opposite direction.

Fig. 14: illustrates the fact that it is notnecessary for flanges to beprovided on all the edges, as, for example, they may be omitted entirelyfrom the end section, here designated 1.

As shown in Fig. 12 an even more unobstructed interior may be secured byforming the box sections with outwardly ofi'set seats for the cornerfastenings, whereby the inner faces of the inner members are broughtsubstantially flush with the interior wall faces of the receptacle.These oil-sets are preferably shaped to correspond to the form of theclamping members, as indicated at 18 in Fig. 13, and are further formedso as to fit into each other when the sections are erected, thereby ineffect keying the sections together preparatory b0 the application ofthe fastenors, and contributing to the security of the structure asfinally assembled.

It is to be understood that the term container is used generically anddoes not refer to particular use.

What I claim as new is:

1. A container comprising separate wall or side sections, inwardprojecting edge flanges thereon, the sections having recesses at thecorners forming openings through the apical corners when the sectionsare set up Copies onus patent may be obtained for and one or more of thesections having entrances separating the ends of their flanges andleading to such openings, and corner fastenings comprising virtuallypyramidal caps having apical recesses therein and inner members havingdiagonal projections adapted to extend through said openings into saidrecesses for connection with the caps.

2. A container comprising separate wall or side sections, inwardprojecting edge flanges thereon, the sections having recesses at thecorners forming openings through the apical corners when the sectionsare set up, said recesses having lateral entrances between the ends ofthe flanges of the sections, and corner fastenings comprising virtuallypyramidal caps having apical recesses therein, and inner members havingdiagonal projections adapted to pass through said openings into saidrecesses for connection with the caps, said projections being larger attheir outer portions than said entrances and having reduced necksadapted to be accommodated therein in the assembling of the container,

3. In a container, the combination of separate wall or side sections,inward projecting marginal flanges thereon, and apical corner fasteningscomprising inner and outer virtually pyramidal members with means foruniting them diagonally through the corners of the assembled container,the flanged sections having outwardly-offset mutually-engaging seats forsaid fastening members.
